Im using the latest version on the repo and I really have had any issues whatsoever with any games until I hit Umjammer Lammy


Apparently this is a known issue but has been resolved in certain emulators

The audio files for the guitar are stored on the CD I guess. I figured I would report it at least as a "bug"


Unfortunately unless im wildly mistaken, PCSX does not play ecm.bin and my conversion using ecm tools doesnt have the guitar audio.
 
The emulation is perfect for everything except for the sound effects which would be played by hitting buttons.

I could try a different ripping tool and dig out my original cd. I usually use magic iso. I also tried the rom from emuparadise and have the same issue with sound.


It reminds me of the issue with sonic cd, if you didnt have the cd rom (In my case a ridiculously scratched cd), or mount the iso as an actual cd, you could play the game but not have audio. Which was a real shame the US version had great audio.
 
Interesting, I suspect it uses more obscure/rarely used SPU features for guitar effects, so it's probably not a cd image issue.


I'll have a look.
 
Spent half of the day on this one and got it working (as expected it relies on almost never used decode buffer and reverb read behavior), should be good on the next release.
